I am aware that some games (like the early Final Fantasy titles, Disgaea) which are on PSP (more appropriately, PSN) are later versions with a small amount of extra content. Normally it is fairly easy to find this information out with a bit of searching.
However I have not been able to find anything on the differences (if any) between Breath of Fire III as a PSN download for the PSP go and the original on PSX. Can anybody enlighten me? Also, is there some better way to find out this kind of information than blindly searching the internets with Google?
